RUDOLPH J'. ALTGELT, OF SOUTH BEND, INDIANA, ASSIGNOR TO OLIVER CHILLED PLOW WORKS, OF SOUTH. BEND, INDIANA.

PLOW.

Application filed May 23,

To all whom it may concern:

Be it known that I, RUDOLPH J. ALTGELT, a citizen of the United States, and a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and uSe the same.

This invention relates to improvements in plows and more particularly to a frame construction embodying beams having downwardly bent rear end portions forming standards for connection of the plow bases, one object of the invention being to so construct the plow frame of the class specified that those portions where the standards are formed shall be reinforced where the greatest strain comes when the plow is in use.

With these and other objects in view the invention consists in certain novel features as hereinafter set forth and pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan View of a plow frame showing an embodiment of my invention, and Fig. 2 is a side elevation.

In the embodiment of the invention shown in the drawings, the frame comprises a plurality of plow beams 1-2. The forward ends of these beams are connected by a cross-bar 3 and their rear end portions are curved downwardly forming plow standards 1-5 for the reception of suitable plow bases not shown. The beams of the frame as well as the standard portions are made of flat bar metal and the rear portions of said beams are connected by a diagonal brace 6 of metal having substantially the same crosssection as that of the beams. This brace is provided at its respective ends with extensions 78 which lie parallel with the rear portions of the beams and parts of the standards and are securely bolted to both.

The portion of the plow beam 1 and its curved standard part 4 which are subjected Specification of Letters Patent.

to the greatest strains when the plow is in use extends approximately from the point 9 to the point 10 and those portions of the plow beam 2 and its standard 5 which are subjected to the greatest strain extend from the point 11 to the point 12. In order to reinforce these portions of the structure, I employ brace bars 1314 (preferably having the same cross-section as that of the beams and standards) and these brace bars are secured to the outside of the respective beams and standards so as to extend slightly beyond the portions which are subjected to the greatest strains. It will be observed that the brace bars 13 and 14 lie flatly against portions of the beams and standards; that their rear portions are curved in conformity to the curvature of the standard portions of the beams and that the same bolts which secure the brace extensions to the beams and their standard portions may also secure the major portions of the reinforcing bars 13-14 in place.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

An implement frame comprising a plurality of beams connected at their forward ends and provided at their rear ends with downwardly curved standard portions, a

brace connecting said beams and provided at its respective ends with extensions lying against and secured to the inner rear portions of the beams and curved portions of the standard, and reinforcing bars lying against and secured to the outer faces of the rear portions of the beams, said reinforcing bars having curved rear portions conforming to the curvature of portions of the standards and secured to the same.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
